   // 1.沙盒（sandBox）
   // Documents(文件文档， 用户数据主动存储)
   // Library（资源， 一半用来存放，程序员要存储的一些数据）
   // Caches（缓存文件）

   // tmp （临时目录， 下载的临时文件一半放在这里）

 // 2.获取沙盒路径
   //快捷获取到对应目录的 C 函数
    //根目录 家目录
   NSLog(@"Home----%@",NSHomeDirectory());
   //临时目录 tmp
    NSLog(@"Temporary----%@",NSTemporaryDirectory());
    // C函数
   // 参数1:搜索哪个文件夹路径
//    常用 NSDocumentDirectory NSLibraryDirectory
   // 参数2:在用户作用与下搜索
   //参数3： yes or no yes代表绝对路径（基本上都用绝对）， no代表相对路径

    // 1> 将文字写入本地

   //6》 将字典 读入
    NSDictionary *nameDictionary = [NSDictionary dictionaryWithContentsOfFile:dictionaryPath];

  // 7》 将Data 类型写入本地
    UIImage *image = [UIImage imageNamed:@"welcome_2"];

//    2.复杂对象文件读写， 自定义类型
    // 归档／反归档， 序列化／反序列化
   //1> 归档， 将 对象 存储到本地

//    2. 反归档
  Book *huangBook = [NSKeyedUnarchiver unarchiveObjectWithFile:bookPath];
    NSLog(@"%@", huangBook.bookName);
    
    
//    如果对象想要实现归档／反归档
  //1. 对象对应得类需要签订<NSCoding>
  //2. 实现协议方法
  // 1> initWithCoder 反归档用
  // 2> encodeWithCoder 归档用
  //3. 归档时使用NSKeyedArchiver
  //4. 反归档时， 使用NSKeyedUnarchiver
